Feat Prerequisites and Custom progression

So, this may come from my own perspective on what I’m used to in games based off of systems like pathfinder, but I think a small feature that could be handy would be to have more control over the prerequisites for Feats, and how class progression works.

For example, if implementing Feats to be able to wear heavier armour on a class that doesn’t have that feature by default, making it that they need to take “Light armour” before they can take “Medium armour” before they can take “Heavy armour”.

Meanwhile, a class that has “Medium armour” as a default feature, can still take the “Heavy armour” trait as a feat.

Also a way to set as part of class progression “Feat Slot” for any feat, or feats of a particular category, giving more control over class and subclass progression so the creator can know when new feats are unlocked and which classes get access to which feats.
